Description : Vintage synth demo by RetroSound Roland Jupiter-4 Analog Synthesizer (1978); For me is the JP-4 the Jupiter synth with the most interesting sound. Sorry JP-8 :) Four voices. These are nearly always „out of tune", them are never correct. But makes for one possible so outstanding musical sound. more info: www.retrosound.de and http Unfortunately it came by the youtube sound compression to a few unwanted digital noises in the sound. For better sound quality (stereo) add "&fmt=18" without quotes to the end of the URL or use the following link: www.youtube.com
